Solve for p in the literal equation 3p + 41 =q.

Suppose Z denotes the set of all integers, Z denotes the set of all positive integers, and Z− denotes the set of all negative in

ikadub [295]

Answer:

a) False

b) False

Step-by-step explanation:

We are given the following information:

Z is a set of all integers, $Z^+$ is a set of all positive integers and $Z^-$ is a set of all negative integers.

Q is a set of all rational numbers, $Q^+$ is a set of all positive rational numbers and $Q^-$ is a set of all negative rational numbers.

N is a set of all natural numbers.

a) False

We will show this with the help of a counter example.

$Z = 3\\Q = \frac{3}{4}\\\displaystyle\frac{Z}{Q} = \displaystyle\frac{3}{\frac{3}{4}} = \displaystyle\frac{8}{3}$

which is a rational number and not an integer.

b) False

We will show this with the help of a counter example.

$Z = 3\\Z^- = -5\\\displaystyle\frac{Z}{Z^-} = \displaystyle\frac{3}{-5} = -\displaystyle\frac{3}{5}$

which is a rational number and not a natural number.

1 Mrs. Castro has 100 spoon and 80 forks if she put them in buckets what is the biggest number of spoon or forks that bucket wil

Yuri [45]

Answer:

10

Step-by-step explanation:

Here, we want to get the biggest number of spoon or forks that the bucket will have

What we have to do here is to simply find the greatest common factor of 100 and 80

Finding the greatest common factor of both will

give the biggest number of spoon or forks that the bucket will have

Mathematically, the greatest common factor of 80 and 100 is 10

12x+7<-11 or 5x-8>40

DaniilM [7]

Answer:

A

Step-by-step explanation:

Given

12x + 7 < - 11 or 5x - 8 > 40

Solve each inequality

12x + 7 < - 11 ( subtract 7 from both sides )

12x < - 18 ( divide both sides by 12 )

x < - $\frac{3}{2}$

OR

5x - 8 > 40 ( add 8 to both sides )

5x > 48 ( divide both sides by 5 )

x > $\frac{48}{5}$

Solution is

x < - $\frac{3}{2}$ or x > $\frac{48}{5}$ → A

( Math ) Please explain how you got this answer! Please use substitution method!

disa [49]

Answer:

y = 1

x = -2

Step-by-step explanation:

During the substitution method, you are substituting one function into another. Because both functions are set equal to "x", you can make the functions equal each other. This allows you to 'get rid' of the "x" variable and simplify to find the value of "y".

5A) x = -2y

5B) x = 2 - 4y

-2y = 2 - 4y <----- Set both equations equal

2y = 2 <----- Add 4y to both sides

y = 1 <----- Divide both sides by 2

Now that you know what "y" equals, you can plug that value into the "y" variable into one of the equations. This will allow you to then simplify and find the answer for "x".

x = -2y <----- Equation 5A

x = -2(1) <----- Plug 1 into "y"

x = -2 <----- Multiply -2 and 1
